The affiliate-toolkit - WP Affiliate Plugin with Amazon plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'atkp_product' shortcode in all versions up to, and including, 3.7.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is a bypass to CVE-2024-10227.

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid WordPress account with at minimum Contributor role privileges on the target site - unauthenticated exploitation is not possible per CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.4 (Medium) is driven by the scope-changed, network-accessible, low-complexity vector (AV:N/AC:L/PR:L), tempered by the low confidentiality and integrity impacts (C:L/I:L) and the requirement for contributor-level authentication (PR:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or compromises a contributor-level WordPress account on a target site running affiliate-toolkit 3.7.0 or earlier. The attacker creates or edits a post or page, embedding the 'atkp_product' shortcode with a crafted attribute containing a JavaScript payload (e.g., a cookie-stealing script). … |
| Remediation | An upstream code fix is available via WordPress plugin repository changeset 3227483 (https://plugins.trac.wordpress.org/changeset/3227483/), which addresses the sanitization deficiency in atkp_output.php; however, a specific patched plugin version number is not independently confirmed from the available data - administrators should update to the latest available version in the WordPress plugin directory and verify the changelog for a fix referencing CVE-2026-15296 or CVE-2024-10227 bypass. … Detailed patch versions, workarounds, and compensating controls in full report. |
